The formation of adequate mental health systems within prisons has accelerated as a result of successful class action lawsuits. Our recent national survey questioned all state correctional departments about the existence of standards in each system, compliance with such standards, prevalence of class action lawsuits involving the issue of providing adequate mental health services for inmates, issues related to consent decrees, available mental health resources within the correctional system, and the administrative structure of the mental health system. Our purpose was to identify those factors correlated with certified class action lawsuits involving issues related to mental health services. Twenty-one states were involved in such litigation. Only the presence of psychiatric hospitals operated by the department of corrections correlated with the presence of certified class action lawsuits involving mental health services. Prison systems larger than 15,000 inmates were at higher risk for such litigation. Smaller systems having psychiatric hospitals run by the state mental health agency appeared to be at less risk for such litigation.  相似文献

Bone fragments were stored in water for 2 years at room temperature and investigated serologically using the following methods: Absorption-elution, extraction of blood group substances and immunohistochemistry (PAP). All 3 methods gave essentially specific results for fresh bone tissue but with putrid bone tissue unspecific reactions were found predominantly with the absorption-elution and PAP techniques. In contrast, more specific reactions were obtained from the extracts although they were much weaker. From this it can be concluded that pure physical binding plays a substantial role in the unspecific reaction between antibodies and bone material. It is suggested that the relevant physical properties are altered by putrification.  相似文献

This paper addresses two neglected areas in the research on the relationship between family violence and violence outside the home: violence other than parent-child abuse and the effect of gender. Specifically, we consider both parental and sibling violence as independent variables, nonfamily violence as the dependent variable, and gender as the specification variable. The data were collected from a sample of 306 students in Introductory Sociology and Social Problems classes. The finding of particular importance is that the interaction between the gender of both the aggressor and the victim has a significant effect on the relationship between violence within the home and nonfamily violence.  相似文献

This paper explores the capacity of alternative theoretical perspectives to explain the self-reported criminality of black and white young adult females. When criminal involvement is regressed on the theory operation-alizations separately by race, a key difference emerges: For white women, significant effects are clustered in the social-psychological theory groups (bonding, attitudes, and maturation), but for the black women the social-psychological variables have only scattered and inconsistent eflects. Instead, for black women structural indicators emerge as the important predictors of criminal involvement.  相似文献

Most studies that consider the factors influencing the decision to leave an abusive relationship rely on retrospective, self-report data. In addition to the biased samples that are frequently obtained in such investigations, the methodological shortcomings of survey research limit its explanatory power, particularly when applied to such sensitive topics as family violence. This report introduces an alternative method for studying the decision to leave an abusive relationship. Forty-five men and 68 women were studied using an experimental computer game of an abuse-like relationship. The tendency to leave this relationship was measured under four differing conditions of severity and frequency of abuse. A logit analysis revealed that the frequency of abuse was more consequential to women's decisions to leave, while severity of abuse was more salient for men. In addition, the hypothesized model, including frequency of abuse, severity of abuse, and locus of control, fits well for women but not for men. The implications of these findings, as well as the validity and future application of experimental games, are discussed.  相似文献

This article examines voluntary mediation and provides suggested criteria for attorneys in deciding whether or not to use mediation. The author discusses what mediation has to offer, what it takes to make it work, and important cautions for attorneys in deciding about the use of this process.  相似文献
